Ct)e Sntoentor's prologue.

I went with him to build the Keystone 

Zinc Compa orks at Birmingham, 

Pennsylvania. I think he left the Birmingh ks and 

went to Bayonne, New Je remaining as 

manager of the Birmingham \ 

C. Mr. Charles Willi Philadelphia chemist, after- 

wards professor of chemistry at the State School of Mines, 
Rolla, Missouri, was employed as chemist :o assist me, or 
direct me, and he would spend about two days of each 
month at Birmingham. The bah the tim( - in 

Philadelphia. 

<L It came up in my mind, "Why do they not make white 
lead by the same process used to make white zinc — sublime 
it with fire and catch it in bag This often came up in 

mv mind and it annoyed me so much that one day 1 put

the question to Mr. Williams. His answer 

was that it was impossible. I suppose 

that I am of an inquiring mind, at 

, least I asked him why it was impos- 

KMi$ sible. He turned around to me 

r and said, " You're a fool." That 

^ped all talk between him and me 

ret. Of course I went on and 

although I had some trouble. 

5 after, in reacKig Percy's Metallurgy of Lead 

I found that he said it would be possible to 

and gases from lead fumes by using some kind 

>ric as a strainer, if it was not for the heat and 

: acid. If Mr. Williams had explained to me 

impossible >uld not be asking me to

checking, it being so hard and brittle. Sublimed White 
Lead has the good qualities of zinc, being made with fire, 
and the good qualities of carbonate of lead, without any 
of the bad qualities of either. 

C. After years of exposure a paint film of Sublimed White 
Lead remains white, firm and solid, and presents an excellent 
surface for repainting. No special preparation of the sur- 
face is necessary, and the old paint film will take and hold 
a new coat to the satisfaction of the most exacting painters.

stage the charge is subjected to a heat sufficiently intense 
to vaporize the lead contents with sufficient access of air to 
oxidize it into a basic sulphate compound of lead. 
C Powerful suction fans carry these volatilized vapors 
through a long series of sheet iron pipes cr flues, up around 
and through the famoi i being 

completed during the progress, until the cooled and c< 
densed white vapors of lead oxy-sulphate are I Elected 

in fabric condensers, which allow the gases of combustion 
to escape through their meshes. These condensers or col- 
lectors are in the form of lonp; baes, hunp- oerDendicularlv

C When it is remembered that in this j a pure 1< 

nent is carried in the form cries of 

winding flues for a distance of pra one thousand 

feet, until it is finally caught and retained in the fabric 
strainers (bags), it will be realized that the pigment par- 
ticles must be in a fine state of subdivision. As a matter of 
fact these ultimate particles of drv Sublimed White Lead are 
so fine as to be practically formless — perfectly amorphous. 
Many pigments, especially those torn 
of precipitation, 
sion, etc., are 
crystalline or crypto- 

talline, to use the 
chemical term; but no 
other pigment, except 
lamp black, approac 
sublimed lead in fine- 
ness and absence of 
structure; and there is no 
other pigment to which it 
can be compared in dura-

and to substitute for the fragility of lead carbonate, with its 
tendency to "go dead," to "check" and "chalk," the 
stable unchanging solidity of Sublimed White Lead. This 
pigment in combination with zinc alone, or with zinc and 
corroded lead would seem to make attainable the highest 
possible type of ready mixed paint, in which the known 
virtues of each would be utilized to the fullest extent, while 
the inherent defects of each are fully corrected by the 
others. The practical experience of the leading paint 
manufacturers has completely established the truth of this 
deduction.
